Position Details

Location: Los Angeles (Hawthorne), CA

Employment Type: Full-time

Department: Starlight Solar

Travel: Occasional

The Mission

Starpath develops and manufactures the technologies that will enable humans to live on the Moon and Mars. Today, we are building robotic systems that locally produce the essential commodities a lunar civilization will require at extreme scale: water, power, and oxygen. Our ultimate goal is to build and operate a self-sustaining city on Mars.

Chemical / Materials Engineer – Space Solar

The Starlight team is focused on dramatically improving space solar power to support Starpath's core mission and the greater space economy. Starlight manufactures the lowest cost and highest performance space solar ever, which will power the majority of new satellites built on Earth and all of Starpath's equipment on the Moon and Mars.

As a Chemical / Materials Engineer on the Starlight team, you will work alongside our senior chemists on the materials and chemistries behind our solar cells and encapsulation systems. You'll support development, characterization, and scale-up work across cell chemistry, polymer encapsulation, and barrier systems — running experiments, building process workflows, and translating bench-scale chemistry into stable, reproducible manufacturing.

Responsibilities

Support development and optimization of chemistries and processes across cell materials, polymer encapsulation, and barrier systems

Run experiments, characterize materials, and analyze data to inform chemistry and process decisions

Build and maintain lab workflows, sample tracking, and characterization pipelines that support fast iteration

Perform materials and device characterization using techniques such as XRD, XPS, FTIR, DSC, TGA, SEM, photoluminescence, IV, and stability/degradation testing

Partner with senior chemists on root-cause investigations connecting chemistry to device and encapsulation performance

Support scale-up of bench-level chemistry into stable, reproducible processes on the manufacturing line

Contribute to environmental stability strategies — moisture, oxygen, thermal, UV, and radiation tolerance

Maintain lab safety, chemical inventory, and contamination control practices

Push back on unnecessary complexity — simplify chemistries, reduce process steps, and cut overhead wherever it doesn't add value

Required Qualifications

Bachelor's or Master's degree in chemistry, chemical engineering, materials science, applied physics, or a related discipline

1+ years of hands-on experience with thin-film photovoltaic, optoelectronic, polymer, or related materials (internship and academic research applicable)

Working knowledge of materials characterization techniques and the ability to interpret chemical, thermal, and electrical data

Demonstrated ability to run experiments, collect and analyze data, and draw conclusions from bench work

Preferred Qualifications

Master's degree in a relevant discipline

Direct experience with thin-film PV, OLED, OPV, or related solution-processed optoelectronic materials

Hands-on experience with polymer chemistry — encapsulants, adhesives, barrier films, or bonded joints

Experience with solution-processed deposition methods (spin coating, blade coating, slot-die coating) or polymer curing and lamination

Proficiency with common characterization techniques — XRD, XPS, FTIR, DSC, TGA, SEM, AFM, photoluminescence, IV, EQE

Experience translating bench chemistry to larger-area or pilot-scale processes

Familiarity with glovebox operations, cleanroom protocols, and chemical safety

Experience using Python, MATLAB, or comparable tools for data analysis

Exposure to aerospace, space, or other high-reliability hardware environments
